This is a 092-0130R-1500 25.4 mm Dia. N-BK7 Protected Gold Spherical Plano-Concave Mirror, a high-quality optical component sourced from EKSMA Optics. The mirror has a base shape of a circle with a diameter of 25.4 mm and a thickness at the edge of 6 mm.
The mirror's geometry is spherical, with a radius of curvature (R1) of -1500 mm, resulting in a focal length (EFL) of -750 mm. This concave mirror is designed to focus light at a point on the opposite side of the mirror from the light source.
The mirror is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transmission range. The coating on the front surface is EKS 0030protgold900, a protected gold coating that provides high reflectivity in the near-infrared region, specifically at 900 nm. This coating ensures high-quality reflection and durability, making it suitable for various applications.
